I'd say the 150-something is definitely in the genoa category, and the 109 is the working headsail. Regarding jib tracks, Randy, when you say cabin deck, do you mean on the housetop, or the combing top? I'm not sure the cabintop is a good choice as the broader you reach, the more the shrouds will interfer with the sheet lead. The combing is an option probably...you'll be able to sheet in closer from that position than the toe rail. My 5 cents. t Tom Smith & Jane Van Winkle M17 #496 -- dharma bum -----Original Message----- From: montgomery_boats-bounces+tsmith=nextit.com@mailman.xmission.com [mailto:montgomery_boats-bounces+tsmith=nextit.com@mailman.xmission.com] On Behalf Of Randy Wirth Sent: Tuesday, August 08, 2006 12:37 PM To: montgomery_boats@mailman.xmission.com Subject: M_Boats: Working Jib Hi, I just replaced my original working jib with one made by Ullman sails. It came in with a deeper foot but not nearly as much material along the leach line. I have been told that if I install jib tracks on the cabin deck that I will have more power and more control over using my old system of using the aluminum toe rails with pulleys. I am trying to decide whether to have a larger sail cut or to install the tracks, pullys, cleats. I would welcome suggestions. What is the size of the original working jib? I had thought it was a 152 but have been told 109.
